Introduction to Exponential Functions
Students will define and graph exponential functions, identifying key features like intercepts and asymptotes.
Key Questions
- Explain the defining characteristics of an exponential function.
- Compare the growth rate of exponential functions to linear and polynomial functions.
- Analyze the role of the base in determining the growth or decay of an exponential function.

About This Topic
The impact of social media focuses on how digital connectivity influences mental health, social structures, and friendship. For 11th graders, this is a highly relevant topic as they navigate their own digital lives. Students analyze the ethical implications of their digital footprints and how different cultures use social media for both personal and political purposes. This aligns with ACTFL standards by using interpretive reading and listening to explore modern media and its connections to social behavior.
Since students are already experts in using social media, the goal of this topic is to move them toward critical analysis. Active learning strategies like 'digital footprint' audits and structured debates about online ethics allow students to reflect on their own habits. By comparing their experiences with those of peers and people in other cultures, they gain a broader perspective on how technology is reshaping human interaction. This approach turns a daily habit into a subject of serious academic inquiry.
Active Learning Ideas
Stations Rotation: The Ethics of Connectivity
Students move through stations that present different ethical dilemmas related to social media (e.g., privacy, cyberbullying, misinformation). At each station, they discuss a potential solution and record their thoughts.
Think-Pair-Share: Digital Footprint Audit
Pairs discuss what their digital footprint might say about them to a future employer or a person from another culture. They brainstorm ways to ensure their online presence reflects their true values.
Formal Debate: Social Media and Mental Health
The class debates whether social media does more to connect us or isolate us. They must use evidence from articles and personal observations to support their claims in the target language.
Watch Out for These Misconceptions
Common MisconceptionStudents often believe that what they post online is private or temporary.
What to Teach Instead
Teachers should use real-world examples of how 'deleted' content can resurface. A hands-on activity where students 'trace' the path of a post helps them visualize the permanence of the digital world.
Common MisconceptionThere is a belief that everyone uses social media in the same way.
What to Teach Instead
By researching social media trends in different countries, students can see how cultural norms influence online behavior. Comparing popular platforms in the US versus China or Brazil highlights these differences.

Planning templates for Mathematics
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
rubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
